Posttraumatic Stress Disorder (PTSD)

Post-Traumatic Stress Disorder (PTSD) is a natural emotional reaction to
a deeply shocking and disturbing experience. It is a normal reaction
to an abnormal situation. Often, the events that cause PTSD are difficult
to document, making it nearly impossible to substantiate
a claim for VA benefits. We cannot underestimate the power
of being mutually supportive in dealing with the VA for PTSD claims. Men
who have no records of events or Medals sorely need our assistance with
hand written letters confirming their stressor event. By this effort
YOU can be the difference maker in someone's quality of life
in their retirement years. Please
help each other!

This is the form used for evaluation of PTSD and will help you understand
exactly what is needed. You should pay particular attention to part D, where
it mentions exposure to traumatic stressors. In other words, you must have
your story well thought out before you get there. You only get one chance
to make the bad impression here.
